So if my barcode text were: this is a test
And I have the barcode setup to generate and show the checksum text, should I get an error? I get an error stating that: The character 't' is illegal in code 39. Shouldn't it be allowed under the extended 3of9 barcode? - Mitch -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Paulo Soares Sent: Thursday, May 03, 2007 10:25 AM To: Post all your questions about iText here Subject: Re: [iText-questions] Code39 Extended & Checksum That's correct. The barcode 39 extended is just a convention where the $, /, %, and + symbols act as "shift" characters. The checksum is done over the "normal" symbols, before interpretation by the reader.
